*	percpu: Omit segment prefix in the UP case for cmpxchg_double	Christoph Lameter	2011-03-27	1	-4/+10
\| \| \| \| \| \| \| \|	Omit the segment prefix in the UP case. GS is not used then and we will generate segfaults if cmpxchg16b is used otherwise. Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
*	percpu, x86: Add arch-specific this_cpu_cmpxchg_double() support	Christoph Lameter	2011-02-28	1	-0/+59
	Support this_cpu_cmpxchg_double() using the cmpxchg16b and cmpxchg8b instructions. -tj: s/percpu_cmpxchg16b/percpu_cmpxchg16b_double/ for consistency and other cosmetic changes. Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Tejun Heo <tj@kernel.org>
